In this post, I’d like to share details about the “upgrade and setup of our internal NAS” that we recently carried out in-house.
The new device we installed is the “UGREEN DXP4800 Plus.”
I set it up using the dedicated app while effectively reusing the SSDs we already had on hand, and the process turned out to be much easier than I expected.
1.Previous Environment and Current Configuration
Previously, we had set up “FreeNAS (now TrueNAS)” on a Windows machine to run our file-sharing environment. As part of the upgrade of our current internal server, we’ve decided to upgrade the NAS as well.
This Issue’s Focus (Effective Use of Assets)
For the drive, I decided to reuse two 4TB SSDs that had originally been used to back up our internal server.
My goal was to create an environment that offered the “silent operation” and “high-speed access” unique to SSDs while keeping costs down.
2.Actual Setup Using the Official Procedure and Dedicated App
I followed the official quick start guide and used the dedicated app to complete the setup.

System Configuration
Main Unit: UGREEN DXP4800 Plus (4-bay / Intel Core processor / supports 10GbE high-speed LAN ports)
Storage: 2 × 4TB SSDs (reused from the in-house server backup system)
Actual Setup Procedure
1.Hardware Installation
I unlocked the tray, pulled out the drive tray, and installed two 4TB SSDs.
I was a little unsure at this point. For 2.5-inch drives, you need to remove the screw located at the right edge of the tray.
I installed them in the unit, turned on the power, and connected the 10GbE LAN port to the network.


2.Initial Setup and Account Registration Using the Dedicated App
Download the “UGREEN NAS App” onto the new server and pair the device by following the on-screen instructions.
First, I created an “administrator account” to manage everything.

3.Creating a Storage Pool (RAID 1)
To prepare for the unlikely event of a drive failure, we configured a RAID 1 (mirroring) setup using two SSDs, creating a configuration that safely stores data in duplicate.

4.General Account & Shared Folder Settings
In addition to the administrative accounts, we added “general accounts” for employees to use in their daily work. We assigned access permissions to shared folders and set up an environment that ensures secure use.
5.Thoughts
Through this setup process, I felt that it was much easier than when I previously set up FreeNAS on Windows.
With the UGREEN DXP4800 Plus, all I had to do was download the dedicated app and follow the on-screen instructions.
3.Summary
Without wasting our existing SSD assets, we were able to use the app to quickly upgrade to a secure and user-friendly in-house NAS environment!
Going forward, we plan to implement a regular backup schedule so that our entire team can make the most of our data.
That concludes my presentation.
